M USICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 595,366, dated December 14, 1897.

7 Application filed April 1, 1897. Serial No. 680,239. (No model.)

To all. whom it may concern.-

Be it known that I, GUSTAV A. BRACHHAU- SEN, residing at Rahway, Union county, State of New Jersey, have invented certain new and useful Improvements in Musical Instruments, of which the following is a full, clear, and exact description.

Heretofore in the manufacture of musicboxes of the type which employ note-disks to operate the musical instrument it has been customary to support the motor for driving the disk upon the bed-plate, which likewise formed the support for the musical instrument proper and for other portions of the device. The motors in these instruments were supported by the bed-plate intermediate of its ends, usually at about midway between the ends. In large-size instruments these bed-plates are over thirty inches long and the motor alone Weighs about forty pounds, so that it will readily be understood that the weight of the motor upon the bed-plate retards the vibrations thereof produced by the musical instrument proper, and hence reduces the efficiency of the instrument.

The object of my invention is to overcome these and other difficulties heretofore found; and to this end my invention consists in the novel arrangement and combination of parts hereinafter described and claimed.

In the accompanying drawings, wherein like characters represent corresponding parts, Figure 1 is a fragmentary plan view of a sufficient number of parts of a note-disk musicbox to illustrate my invention. Fig. 2 is a vertical section of the same on the line 2 2 of Fig. 1.

The main casing A may be of any suitable or preferred construction and supports at one end thereof a suitable motor 13, which opcrates the note-disk a in the usual manner. Upon the motor is secured one end of a bed plate 0, as indicated at b. The other end of this bed-plate is supported upon the casing, as indicated at'c. Upon the bed-plate C is supported the sounding device or musical instrument proper, D, which in the present instance comprises one or more sets of combs which are vibrated by star-wheels d, operated by the note-disk a in the usual manner. The note-disk a is likewise supported upon the bed-plate 0 through the central pin and sleeve 6 or in any desired manner. The means for maintaining the note-disk a in operative position comprises a hinged rod f, with antifriction-rollers g and locking-latch h, all of the usual construction. These means forsecuring the note-disk are likewise secured to and supported upon the bed-plate C. By my construction it will be observed that the bedplate 0 is free to vibrate intermediate of its ends and that there is nothing whatever between the lines wand .ein Fig. 1 to retard the vibrations of the bed-plate and the parts carried thereby. Furthermore, it will be seen that the motor and bed-plate being united it is impossible for the relation of the parts to be changed and that no adjustment of the parts with relation to each other is necessary in mounting the instrument in the casing.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a music-box, the combination with a casing, a motor secured thereto and a bed plate with a sounding device supported thereon, said bed-plate being wholly supported by the motor at one end and by the casing at the other end, whereby the bed-plate is free to Vibrate intermediate of its ends.

2. In a music-box, the combination with a casing, a motor secured thereto and a bedplate with a sounding device and its operating mechanism supported thereon, said bedplate being wholly supported by the motor at one end and by the casing at the other end, whereby the said bed-plate is free to vibrate intermediate of its ends.

3. In a music-boX, the combination with a casing, a motor secured thereto, a bed-plate with a sounding device supported thereon, a note-disk and means for securing the same in operative position, said note-disk and the securing means therefor being supported by the bed-p1ate, said bed-plate being wholly supported by the motor at one end and by the casing at the other end, whereby the bed plate is free to vibrate intermediate of its ends.
